Abstract: In one embodiment of the present invention, the liquid crystal display device of the invention performs an overshoot drive, including: an LCD having a liquid crystal panel for displaying video image; a frame memory installed outside of the LCD; and lookup table, the table with which third gray scale data most suitable for performing the overshoot drive to the LCD can be computed based on first gray scale data of a first frame and second gray scale data of a second frame, where the second frame is a frame right before the first frame and is stored in the frame memory in advance, wherein lookup table data is stored for each response speed characteristic of the LCD. Thus, without rewriting of lookup table data, the liquid crystal display device having the lookup table most suitable for performing the overshoot drive is realized while high display quality is maintained therein.

Abstract: In one embodiment of the present invention, when a still image is displayed, applied voltages respectively corresponding to a total of n (n being an integer of not less than 4) types of gradation 0 to (n−1) are outputted to pixels. When a moving image is displayed, an applied voltage corresponding to a predetermined gradation m (1≦m≦(n−2)) is applied to the pixels instead of applied voltages respectively corresponding to gradations of less than the predetermined gradation m. Overdrive driving is performed with respect to a total of n types of gradation.

Abstract: The present invention provides a liquid crystal display panel that has an enhanced liquid crystal alignment controlling force irrespective of the external conditions or environments. The enhanced liquid crystal alignment controlling force sufficiently prevents surface roughness or color unevenness that can occur depending on the viewing angle, so that favorable display qualities and excellent transmittance can be achieved. The liquid crystal display panel includes a pair of substrates comprising a pixel electrode and a counter electrode; and a liquid crystal layer disposed between the substrates, the liquid crystal display panel comprising spacers at at least four corners of a pixel defined by the pixel electrode.

Abstract: In a liquid crystal display device (20), a liquid crystal panel (14) is divided into a display region (15a) including a plurality of pixels (10a) and a display region (15b) including a plurality of pixels (10b). A memory circuit (1) is provided to each pixel (10a) included in the display region (15a). The memory circuit (1) is capable of storing a data signal supplied from a signal line (3). As such, writing the data signal, which has been stored in the memory circuit (1), into a pixel electrode (2) allows an image to be displayed in accordance with the data signal. That is, in the display region (15a), it is possible to display an image without supplying image data from the outside via a scanning line (4) and the signal line (3). This allows a reduction in electric power consumption.
